SDATA
SDQM
ADDR
SDCS
[3:0]
Note:
1. Timings are shown with CAS latency = 2
2. The SDCLK signal may be phase shifted relative to the rest of the SDRAM control and data signals due to uneven loading.
Designers should take care to ensure that delays between SDRAM control and data signals are approximately equal
